Apply 'awk' to all files in a directory or individual files from a command line
Hi All,
I am using the awk command to replace ',' by '\t' (tabs) in a csv file. I would like to apply this to all .csv files in a directory and create .txt files with the tabs.
How would I do this in a script?
I have the following script called "csvtabs":
which makes test.txt with tabs. However, this only works for one file (test.csv) which I have to change each time to the file I want to convert. Since I have many files I want to make the process faster.
Alternatively, if the solution is too difficult, how can I alter the script to take in files at the command line. In other words run:
instead
Any help is appreciated,
Cheers,
ScKaSx
